Living where we do we often drive up a mountain in temps well above 100,
also see stop 'n go in 100+ weather.  I used a VW switch (think it was
for fog lights) in the empty slot right below the hazard switch to have
an override for the radiator fan.  I can run the fan at either low or
high speed when I know things are going to get hot (uphill or long
stops) before the needle rises much.

Turning on the heater briefly (30 seconds or so) also helps in extreme
cases, dumping cool coolant into the system w/o throwing a lot more heat
into the interior.  Obviously you have the A/C off at this point so
assume you are getting warm anyway.
